Lamp



FIG. 1 is a perspective view of a lamp showing my design from an inclined angle;

FIG. 2 is a top view thereof;

FIG. 3 is a bottom view thereof;

FIG. 4 is a side view thereof (the opposite side being the mirror image); and,

FIG. 5 is a front view thereof.

The broken lines shown on the drawings depict portions of the lamp that form no part of the claimed design. 

I claim the ornamental design for a lamp, as shown and described.
